Black is 000000, and this color is 0e151b, which means that's not black. Theoretically. XD probably I have high brightness or something, thats why I see it's dark blue when everyone sees pitch black. D:

Even black ink has some tints of blue in it. (Try staining something with black ink, and then try & remove it). It's virtually impossible to produce something that is pure black. It could even be the capping program that adds a tinge of blue to it. It's still close enough to black as to make no difference.

Uh, like I said, it depends on monitor. I see clear difference between his eye color and shadow.Anyways, I tried to see this color on volume 12 cover and apparently his eyes weren't colored there lol. Maybe Arakawa doesn't know his eye color herself :'D

So, I was trying to calculate exactly how close to black they are, percentage-wise, and then I got stuck on whether to take the square root of the sum of the squares, or to just average them out... *laughs* But it's either 85.6% black or 91.9% black, respectively. Or another value if neither method is right...
